Cobalt superalloy UMCo-50
Purchase of UMCo-50 scrap and rejects (2.4778): furnace components, sinter grates, hot shear blades, castings and machining offcuts. The cobalt content (~50 %) makes it a high-value scrap. Fast quotations and collection across Europe.
Cobalt-chromium-iron superalloy (Co ~50 %, Cr ~28 %) resistant to oxidation, thermal shock and hot corrosion, including sulphurous atmospheres and contact with molten copper. Markets: steelmaking and furnaces (grates, supports), glassworks, copper and zinc foundries.
- Forms castings · furnace components · blades · turnings
- Density ~8.05 g/cm³ (indicative)
- Melting ≈ 1380 – 1395 °C
Main elements
| Cobalt (Co) | 48 – 52 % |
|---|---|
| Chromium (Cr) | 27 – 30 % |
| Iron (Fe) | balance (~20 %) |
| Nickel (Ni) | ≤ 4 % |
| Silicon (Si) | 0.5 – 1.5 % |
| Carbon (C) | 0.05 – 0.25 % |
Indicative values (BS ISO 11973, G-CoCr28). Cobalt is the driver of the valuation: keep UMCo-50 castings separate from other furnace alloys (Ni-Cr) during sorting; we analyse every batch.
Physical and mechanical data
| Density | ~8.05 g/cm³ |
|---|---|
| Melting temperature | ≈ 1380 – 1395 °C |
| Thermal shock | excellent: the alloy's strong point |
| Hot oxidation | excellent resistance up to ≈ 1100 °C |
| Hot corrosion | withstands sulphurous atmospheres and molten copper |
Available both as castings (G-CoCr28) and as semi-finished products. Scrap typically comes from furnace and sinter-line revamping.
